I assume your evaporator fan's running & blowing air out the back of the coils?

        I believe the charge is low. Maybe a leak or obstruction? Adding a 3-in-1 means compressor was already having problems. 

        Best advice is to locate a junk 63,90 or 126 with a working compressor and swap it out.

don't know much about soda machine a/c, but I know in an automobile when the line freezes up there is usually a restriction in the line due to the compressor starting to go and the orifice tube (filter) plugs up with pieces of compressor shavings and causes the clog
